(TELEGRAPH) — Three species of carnivorous plant that feed on worms underground have been discovered in the Brazilian savannah.

It could require a re-imagining of The Day of the Triffids – scientists have discovered a new type of carnivorous plant that traps and devours its prey underground.

Botanists have found three plants, all relatives of the popular snapdragon garden flowers, that have an unusual network of sticky leaves underground.

These leaves allow the plants to trap and digest worms, and possibly other creatures, that stray onto their sticky surfaces in the soil.
